mm/compaction.c: clear total_{migrate,free}_scanned before scanning a new zone
[ Upstream commit a94b525241c0fff3598809131d7cfcfe1d572d8c ]
total_{migrate,free}_scanned will be added to COMPACTMIGRATE_SCANNED and
COMPACTFREE_SCANNED in compact_zone(). We should clear them before
scanning a new zone. In the proc triggered compaction, we forgot clearing
them.
